Great 2 Part DoserBy Johnon 6/14/2015

John would recommend this product to a friend

I bought 2 of these to replace an all in one unit similar to the Bubble Magus. These things are huge compared to the pumps in my old unit. Both pumps have a flow rate of 1.67ml per minute, not the 1.1ml as advertised. I hooked them up to Reef Keeper Lite and they are working great so far.

I bought 2 pumps to dose my tank with calcium and alkalinity and they worked great. When I set them up and calibrated them, they were a little over 1.1 per min. so I had to re calculate but wasn't a big deal.

Nice and simple pump for dosing. Very quiet and seems to be working well. Comes with tubing and calibration cup.

Great doser pumpBy Ericon 4/21/2015

Eric would recommend this product to a friend

I bought two of these doser pumps for dosing 2 part solution. So far so good, 2 weeks in. One pump is a little faster than the other, so I left it on calcium since an overdose of calcium is less worrysome than an overdose of alkalinity.

They're running on my Reefkeeper Lite. When using with a controller (which you should do as they should not run for long periods of time consistently) you should put them on mechanical relay switches instead of the solid state switches, as the solid state may not switch them off due to the low power draw of the pumps. Google Triac and your controller name to find out more.

I ordered this doser for my Aquaripure vodka filter. I don't have to get someone to dose the filter twice a week while I'm gone. Makes my life much simpler.

Great pumps, watch the flow rateBy Chadon 4/13/2015

Chad would recommend this product to a friend

These pumps are working great so far and are a good value. However, I bought two for dosing and noticed they flow at different rates, one is much faster than the other so I have had to play around with the timing to get the dosing correct. One is right on at 1.1 ml per minute but the other is almost 2ml per minute.

Good ATO PumpBy Glennon 4/13/2015

Great quiet pumps, but need to be upgraded for use with ApexBy Vincenton 3/30/2015

Vincent would recommend this product to a friend

The reviews here say it all. Great pumps! However if you are going to use this on an APEX you are limited to 2 ports (4/8). If you want to use it on the other ports you will want to get one of these or similar for each pump (Woods 4325C Single Outlet Power Adapter Plug) BRS I suggest you start selling these....

Near perfectionBy Old Salton 1/17/2015

Old Salt would recommend this product to a friend

After years (literally) of dosing 2-part by hand, I bought two of these pumps during the Black Friday 2014 sale. Due to the tight space in my stand/sump area, installation took a bit of thought and time. But once up and running, they are, as my teenage daughter would say, "just sick." I control them with my Reefkeeper Lite's multi-timer function and the levels are always spot on. And now I don't have to train my neighbors in the fine art of dosing 2-part!

Great!By Jeffon 1/11/2015

I bought 2 and have them controlled by my reefkeeper. Easily dose 2.2ml for 24 hours and keeps everything stable.

Great Dosing Pump for KalkwasserBy Jimon 1/9/2015

Jim would recommend this product to a friend

We're using this pump for Kalkwasser dosing from reservoir in basement to display tank upstairs. It works fine, and doses a very slow drip, so can run all night to keep the pH stable.

I had a calcium reactor running on my sps dominant tank for 8 months but just did not like the inability to keep track of all the elements being dosed. Switched over to brs two part with Red Sea additives and couldn't be happier. I have sent in my water to be tested by triton through uniquecorals and nothing but green

Got this pump to dose my 2-part alkalinity solution. Provides a nice slow steady drip and is dead silent. The first time I turned it on I couldn't tell it was running until I saw it slowly turning. Comes with input and output tubing and was super easy to set up. I'm using my Reef Keeper as a timer and it's keeping my alkalinity right where I want it. I would definitely recommend this pump for dosing.

Exactly what I needed.By Matton 12/9/2014

Matt would recommend this product to a friend

Easy to set-up. Easy to calibrate. Works great with controllers for consistent dosing. I used 30 minutes to calibrate my pumps instead of the recommended 10 and I think I got a bit more accuracy with my dosing. Both were very close to the 1.1mL per minute rate, but not spot on so don't forget to calibrate! Very quiet operation and my tank is already more stable.

Very well built unit.By Garyon 12/7/2014

Gary would recommend this product to a friend

The pump is larger than what I expected, but very well built. The hose attachment fittings are secure and ridged. The tubing is supplied with each pump as well. They were recommended by another reefer that has used 3 pumps for over 3 years with no issues.

Got 3 for my tankBy Seanon 12/4/2014

Sean would recommend this product to a friend

I got 3 of these for my tank (Alk, Cal, Mag). I wasn't sold on the reliability of the 3-in-one dosers. Since this equipment can potentially crash a tank, I went with what I felt was the safest solution. I have each of my 3 installed with digital timers.

I wished they had timers that were adjustable down to the second instead of just minute. It would really help people with smaller tanks.

Set up was easy and the product is solid. You can tell its well built all around.

I got this pump, and got iy up and running Kalkwasser 24 hrs a day. I'm not surer if that's a smart thing to do or not, I have a 120 gal reef tank, and will monitor it closely an make adjustments accordingly. ut as far as a "Review" for the pump goes? I really like the setup and it's performance so far, beats the gallon milk jug and lift pump with knots tied in the tubing to get a decent drip. Good pump, basically a "Set it and forget it" type of pump

I have been running these for 3 years and just bought another. I have never had any issues and they work like a charm. In conjunction with my Reef Keeper Controller dosing is easy and I can spread it out over hours to not spike the PH too much.

Good, while it works, and somewhat loudBy Matton 10/29/2014

Matt wouldn't recommend this product to a friend

I have four of these pumps, two which have been in service for about 10 months, and two which I've been using for about 3 months. Overall, they function pretty well, while they last. They're louder than my MP40s, even inside a cabinet.

I would not buy them again. The first two, which have been dosing small amounts (~30ml/day) for less than a year, have both started making loud grinding noises. Unfortunately, I bought them a few months before I started using them, so they're both out of warranty. BRS offered to sell me replacements at a discount, but I'm not going to replace my dosing pumps every year.

I'm going to switch to the Neptune Apex DoS for the future.

Great pump for 2 part dosingBy Romanon 8/19/2014

Roman would recommend this product to a friend

Great pump, highly recommend for 2 part dosing automation with reef timer or controller. It is a little bit noisier than I expected, however it helped me realize that my pump was on when it should't be running (due to old timer stuck in ON position), so I was able to quickly turn it off and avoid a disastrous CA overdose.

My dosing pump doses 0.85 ml per minute, instead of 1.1 ml. But, once you know the speed of the doser, it's all that matters. Except for this little problem, the pump is solid. It's something that seems to last.

I have two of these for CAL& ALK. Makes life so easy for tank care. Necessary buy, do not know what I would do without one. Accurate and easy to install and use.

awesomeBy qon 7/16/2014

Once my calcium uptake started to require me to dose daily, I purchased two dosing pumps for 2-part dosing. Easy setup, easy adjusting. I am using two electronic timers, dosing once a day during the night, separating the Ca and Alk dosing times by several hours. I test my Ca and Alk levels at water change times, but have found that I rarely need to adjust the pumps once they are dialed in.

Great dosing pumps!By Monion 6/26/2014

Moni would recommend this product to a friend

I got two of these a couple months ago, and they've been a great addition to my system. The pumps don't siphon, and can raise a good head of water with very consistent flow, which allowed me to put my dosing reservoirs in a closet away from my display tank. The dosing has been extremely consistent, making the water chemistry of my tank more stable than I ever thought it could be.

Only problem was when I had a programming error with my controller, which left the pumps on for several hours and turned my tank into what looked like a bucket of milk. Certainly can't blame the pumps for that tho - they performed exactly as they should!

The product is great... i use it for 2 part dosing attached to a digital timer that doses in 5 minute intervals 3 times a day.... as my tank requirements increase i can just increase the number of times it runs or length of time per run.... my only complaint is that is requires mounting and when purchased i was under the impression it stands on the ground like the natureef... mounting was not a problem with the attached brackets however i didnt have any wall room under my sump so i built a little pvc tower to mount it and it works just fine
